SEPARABLE FASTENER,

Application filed December 2, 1921. Serial No. 519,381.

To aZZ whom it may concern:

Be it known that I, FRED S. CARR, a citizen of the United States, and aresident of Newton, in the county of Middlesex and State ofMassachusetts, have invented an Improvement in separable Fasteners, of

hich the fol-lowing description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresentinglike parts. 7

This invention pertains to improvements inseparable fasteners. It isamong the objects of the invention to provide a separable fastener inwhich the stud and soc ket are positively locked against separationexcept pursuant to a desired manipulation, and in which a very shortstud may be used.

In the drawings, which show a preferred form of one embodiment of myinvention Figure 1 is a" vertical central section through a preferredform of fastener, being partlyin elevation;

"Fig; 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a section on the line 22 of. Fig. 1, showing the positionofthe parts pursuant to that manipulation which permits separation ofstud and' socket; and

Figs. 4 and? 5 are end and side elevations respectively of a part of thefastener illustrated'in Fig. "-1, and are more fully describedhereinafter.

Referring to the drawings and to the preferred form of my inventionselected "for illustrative purposes, I'have shown a stud includin ahead,5, a, neck 6, and a shank portion "*secured'to a stud-carrying part 8,

which may be a portion of the body of a motor car or the like. Betweenthe head 5 and neck 6 of the stud is preferably provided, asillustrated, a relatively abrupt shoulder 9. The preferred form ofsocket illustrated is secured to socket-carrying fabric 10, which may bea motor car curtain, and includes a casing 11 containing a sprin 12having jaw portions 13 and let adapte resiliently to underlie the head 5of the stud by entering the neck 6 behind the shoulder 9 of the stud. Inthe preferred form of spring illustrated, resiliency is provided to thejaws 13 and 14 by forming the spring 12 of spring sheet metal andcutting away an almost complete annular portion 15 and b slotting thespring at 16 from the stu receiving aperture therein to connect withthis annular cut-away portion 15 -Ojpp'osite 7 the slot '16, the springis slotted at 1 ing l';l by which providesspring locating lugs 19, 19

sprin 12. illusti ated, to penetrate the ,curtain 10 and to be clenchedwithin a guiding andisecuring part on the outside of ulatory portion 24,whichmaybe general I from; the stud-receivingaperture to the;peripherygof the spring. In the ,form'o-f. my inyention illustrated, the spring.121 is held in the cas co, the, closure plate 118 (Fig. 1):,

extending into the slots 16 and17 in the h The casing 11 is preferably,as

provided with prongs 20 adapted gob the curtain 10', thissecura,"

The cylindr cal flange 26 whicli' portions of the socket carrying Themechanism described constitutesaj position in any. I

preferred form offastener in which arela v I tively short stud isadapted to be engagedby, S

jawpmeans located on the same side of the socket-carryingfabric. orcurtain as the stud,;

While providing for manipulation ofthjegj aw means from apart projectingthrqugh the curtain and located on the outside Qt-et curtain on the sidethereof oppositethe stud. When. the manipulatory part. '24; is turned" tY fiQ'th v will press againstthe' adjacent faces 0f the spring inopposite directions and will spread the jaws 13, 14 so that they will nolonger underlie the head 5 of the stud. In the preferred form of myinvention illustrated, it is not necessary to exert an outward pull onthe socket to effect separation of stud and socket pursuant to thismanipulatory movement because I have provided kick-off means typified bythe kick-oil spring 28 located within the manipulatory part 24L andpressing a sliding disc 29 against the outer end of the head of the stud5 so that as soon as the jaws release the head of the stud, the socketcasing, including the spring, will be moved outwardly away from the studso that, if the manipulatory part is again released, the jaws 13, 14:will not again enter the neck of the stud behind the head thereof. Thesliding disc 29 is held in relation to the manipulatory part 24 by theprojections 27.

The operation of the fastener herein de-- scribed is very similar tothat illustrated in United States Letters Patent to Bourque No.1,367,350, issued February 1, 1921. The construction of the fastenerhas, however, been improved from a manufacturing stand point andparticularly in thatits parts have been so reorganized as to admit ofthe location of the jaw-containing portion of the socket on that side ofthe socket-carrying fabric from which the stud enters, so that a veryshort stud may be used. The use of a very short stud is desirable inmany places,

particularly in connection with the fastenings of curtains onautomobiles because of the improved appearance and because clothing,etc., is not likely to be caught and torn on a short stud. For manypurposes fasteners difi'ering considerably in construction and operationfrom the one illustrated may be used to advantage while retaining thebefore-described principal advantages of my 2D invention.

l/Vhile I have shown and described a pre ferred form of one embodimentof my invention, it will be understood that changes involving omission,substitution, alteration and reversal of parts, and even changes in themode of operation, may be made without departing from the scope of myinvention, which is best defined in the following claims.

Claims.

1. A fastener comprising, in combination, a stud having a head and aneck, a casing containing jaw means for engagement in said neck of saidstud behind said head, said casing and jaw means securedto a carryingfabric and located on that side of said fabric from which said studenters, and manipulatory means on the opposite side of said fabric fordisengaging said jaw means from said neck of said stud.

2. A fastener comprising, in combination, a stud having a head and aneck, a casing containing jaw means for engagement in said neck of saidstud behind said head,

gage said jaws from. said neck of said stud. I

3. A separable fastener comprising, in combmation, a stud having a headand .a

neck, and a socket comprising a casing secured to a carrying fabric onthat side thereof from which the stud enters, jaw,

means in said casing, a closure plate for said casing between saidcasing and said, fabric and clenched within a casing-securmg part on theopposite side of said fabric from said casing, and manipulatory meansprojecting through said casing-securing part and permittingstud-releasing movement of said jaw means.

4. A separable fastener comprising, in combination, a stud having a headand a neck, and a socket comprising a casing secured to a carryingfabric on that side.

thereof from which the stud enters, jaw

means in said casing, a closure plate for said casing between saidcasing and said fabric and clenched within a casing-securmg part on theopposite side of said fabric from, said casing, manipulatory means pro-7 jecting through said casing-securing part and permittingstud-releasing movement :of

said jaw means, and resilient means associated wlth said mampulatorymeans for urging said jaw means toward said head of said stud pursuantto disengagement of said jaw means from behind said head of said stud.

In testimony whereof, I have signed my.

name to this specification. I
